For captains: Always remember and forever take heed; left hand for glidepath and right hand for speed!
Primary effects of controls apply.
Do what the autoflight does. If you get slow, put the power up (counter the underslung-pitchup if necessary). If you get high, stuff the nose down! As mentioned earlier by Unhooked, try staying on the glideslope of an ILS with the power and controlling speed with the stick. Entertainment-plus.
The reverse works in a C150 only because of the powerful secondary effect of controls.

True, but that's the secondary effect of controls eventually working. On final, we don't have time to wait. High? Stuff the nose down and then pull the power off a bit, anticipating the secondary effect of controls (push nose down, speed will eventually increase).
